Coherent, non-linear and quantum optics provide paradigms for studying and utilizing ultracold atoms and provide the primary means by which properties of such atoms are measured.Conversely, ultracold atomic gases are attractive media for new experiments and capabilities in optics.These interconnections will be illustrated in discussing several experimental results.I will describe our development of a circular waveguide for ultracold atoms, present an approach to dispersion management of atomic beams propagating in this waveguide, and discuss progress toward the goal of atom interferometry.Second, I will discuss an application of non-linear optics, specifically of superradiant Rayleigh and Raman scattering, to measuring coherence properties of stationary and of propagating atomic gases.Last, I will describe initial results involving cavity quantum electrodynamics with ultracold atomic ensembles, including the observation of non-linear optics at low light levels and ameasurement of cavity-enhanced momentum diffusion of atoms trapped in a cavity.
